2. Description of the Related Art In recent years, in order to prevent such accidents caused by children's lighters, countries which are required by law to mount a mechanism on the lighter that makes it difficult to operate the ignition control lever of the lighter have become the countries of the United States and Canada. , Mexico, Australia, etc. are gradually increasing, and each manufacturer of the lighter industry is currently responding while obtaining a patent for a child operation prevention device that makes it difficult to operate the ignition control lever of the lighter. It is thought that the law stipulates the obligation to install a mechanism on the lighter that makes it difficult to operate the ignition control lever of the lighter in this way, even in Japan and Europe.

There are also lighter ignition levers provided with a lock device, but these are for safety when the lighter is not in use or during transportation, and the lock is released and the ignition operation is performed. It is required to make the series of relationships structurally special by associating with each other and how to associate the two types of contradictory operations with each other to make the ignition operation lever difficult to operate. Therefore, the lock device is a structure that should be distinguished from the structure required from the viewpoint of safety as a child operation prevention device, and the structure that makes it difficult to operate the ignition operation lever of the lighter and the structure of the ignition operation lever of the lighter. It differs from the locking structure of the locking device that disables operation.

Furthermore, there are various types of ignition control lever structures depending on the type of lighter, and there are broadly classified push types that push downward from above and slide types that move horizontally. With a push type lighter, a spring is used in the horizontal direction, and while pushing in the horizontal direction against this spring, unlock the lock and push the ignition control lever of the lighter downward to operate the ignition control lever. Although a mechanism that makes it difficult to perform is known, there is a problem that the number of parts is two because a spring is used and it is difficult to assemble it.

[0005]

SUMMARY OF THE INVENTION Therefore, according to the present invention, a mechanism for making it difficult to operate an ignition operation lever can be provided in a slide type lighter with a small number of parts and is easy to assemble. It is an object of the present invention to provide a child operation prevention device device for a slide type lighter having a structure that can be incorporated by only slightly changing the structure of the operation lever.

[0006]

In a child operation prevention device for a slide type lighter according to the present invention, an opening portion for inserting a horizontal end portion of a lighter ignition operation lever is formed in an operation portion for pushing an upper portion in a horizontal direction. At the same time, a pull-out prevention part is provided so as not to come off from the lighter ignition operation lever, and a flexible hanging part having a stopper part that is integrally provided so as to hang down from the operation part and comes into contact with the tank body at the lower end is provided. A guide part that is movable in the horizontal direction is provided in the flexible hanging part between the operation part and the stopper part, and one end of the lighter ignition operation lever is abutted between the guide part and the stopper part as a fulcrum to make the operation part Characterized by a structure that enables the operation of the lighter ignition operation lever by deforming the flexible hanging part and moving the stopper part out of contact with the tank body when moving horizontally To.

[0007]

Therefore, the child operation prevention device for a slide type lighter according to the present invention has an opening preventing portion for forming a horizontal end portion of the lighter ignition operation lever to prevent the lighter ignition operation lever from coming off. The lighter ignition control lever has a simple structure in which an operating part for pushing the upper part in a horizontal direction and a flexible hanging part that hangs down from the operating part and has a stopper part at the lower end that comes into contact with the tank body are integrally provided. It is easy to attach to the lighter and can be assembled by slightly changing the structure of the ignition control lever of the conventional lighter.

Further, a guide portion for horizontally moving the operating portion is provided at a flexible hanging portion between the operating portion and the stopper portion, and one end of the lighter ignition operating lever is provided between the guide portion and the stopper portion. As the fulcrum is contacted and the operating part is moved horizontally, the flexible hanging part is deformed and the stopper part releases the contact with the tank body, enabling the operation of the lighter ignition control lever. Since the operation part is slid backward and lowered while being slid once in the front direction which is difficult to operate, it becomes very difficult for children to perform the ignition operation.
